hi,
When carrying out headway calcs for a non-stopping train following a stopper, could someone explain how the additional time equates to the Textra = Tdwell + 0.5(Braking time + acceleration time)?

How is the 0.5(Braking time + acceleration time) portion derived? I had a go at deriving it using Newton's laws and substitiution but can't get my head around it!
